The present invention overcomes problems in the prior art of updating/upgrading remote controls to include functions and/or abilities not originally planned when the remote control was being designed/manufactured. A set-top device itself can be an updated device which can be bundled with an outdated remote control. The set-top box can provide a remote teacher display or such a display can be made available from a distance via the internet or satellite. In such a case, a remote control can be used to select a specific on-screen display button from the remote teacher. The corresponding remote control code is then taught to a learning remote control by a blaster driven by the device. In such a case, the device is able to drive a blaster which serves as a substitute for a teaching remote control in order to teach and/or update/upgrade the learning remote control.
